A telescopic tool includes a positioning device mounted between first and second rods. The first rod includes a first positioning hole, and a first gripping portion. The second rod includes a plurality of second positioning holes, and is movable relative to the first rod to align the first positioning hole with one of the second positioning holes. A switch controller is movable relative to the first rod and is movably coupled to a positioning member. The positioning member movably extends through the first positioning hole and is releasably engaged in one of the second positioning holes in response to movement of the switch controller relative to the first rod. A fixing member includes a second gripping portion mounted around the first rod. A resilient biasing member is pivotally connected to the first rod and pressing against the positioning member.

A finger ratchet tool includes a body having a top part on the top thereof, and a ratchet device connected to the underside of the body. The top part includes a tapered face in the outer periphery thereof. Two flanges extend radially from the top part. A connection portion extends from the body. A mounting member has a C-shaped collar which has an opening, and a rod is connected between two ends of the opening. A matching face is defined in the inner periphery of the C-shaped collar. Two recesses are defined in the C-shaped collar and each have two ends. The rod is pivotably connected to the connection portion, and the C-shaped collar is mounted to the top part to match the matching face with the tapered face. The flanges are engaged with the recesses.

A pipe wrench is provided with an extendable handle that fits within a cavity of the head. A lever locks the extended length of the extendable handle along a continuous spectrum between a maximum and a minimum extension of the handle. The lever includes cam surfaces. In an unlocked position, the thickness of the lever between the pivot and a friction plate is less than the thickness between the pivot and the friction plate in the locked position. The friction plate is a composite comprising a top lever plate, a midsection, and a concave surface. The lever plate and concave surface include hard, durable materials, and the midsection is a soft elastic material that redistributes frictional forces across the frictional block. The channel-lock prevents inadvertent overextension and/or accidental removal of the extendable handle.

A wrench extension apparatus is an apparatus that serves to extend the moment arm of a wrench to increase the leverage on a mechanical fastener, so that the mechanical fastener is fastened or loosened easily without much effort from the user. The apparatus may include a breaker bar, at least one proximal protrusion, and at least one distal protrusion. The breaker bar increases the moment arm of a wrench to increase the torque being applied to the mechanical fastener. The breaker bar is also designed to be comfortably gripped without hurting the user's hand. The at least one proximal protrusion and the at least one distal protrusion enable the breaker bar to be engaged with the desired wrench. Further, the at least one proximal protrusion and the at least one distal protrusion enable the breaker bar to be used with wrenches of different sizes without the need to switch wrenches.

A pipe wrench includes a head having a first aperture defining a central axis. The pipe wrench includes a first jaw coupled to the head having a plurality of teeth defining a first contact region, and a second jaw partially extending through the aperture of the head having a threaded portion and a plurality of teeth defining a second contact region. The second contact region extends beyond the first contact region in a direction parallel to side surfaces of the head. The pipe wrench includes a biasing mechanism located within the first aperture to align the threaded portion of the second jaw with the central axis of the first aperture, and an actuator having threads engaged with the threaded portion of the second jaw such that rotation of the actuator moves the second contact region of the second jaw relative to the first contact region of the first jaw.

A wrench includes a body having a head and a handle portion defining a longitudinal axis. The wrench includes a first jaw coupled to the head with the first jaw including first teeth and an edge. The edge defines a width of the first jaw. The wrench includes a second jaw extending through an aperture of the head with the second jaw including a threaded portion and second teeth. The wrench includes an actuator coupled to the threaded portion of the second jaw such that rotation of the actuator relative to the second jaw moves the second teeth relative to the first teeth. A length is measured from the edge of the first jaw to the second end of the handle portion parallel to the longitudinal axis. A ratio of the width of the first jaw over the length is less than 0.06.

A wrench extension assembly includes an elongated member that has a first end, a second end and a top side. The elongated member is telescoping and includes a second section removably extendable into a first section to alter a length of the elongated member from the first end to the second end. The elongated member is straight from the first end to the second end. A first bracket is attached to the elongated member adjacent to the first end and is configured to releasably couple a wrench to the top side such that the wrench extends outwardly away from the first end. A second bracket is attached to a sleeve that is positioned on the elongated member and is slidable between the first bracket and a juncture of the first and second sections. The second bracket is configured to releasably couple the wrench to the top side.

A telescopic socket includes an outer sleeve, an inner sleeve, and a jointing ring. The outer sleeve includes at least one abutting ball, plural first concave portions, and plural first protruding portions. The inner sleeve is sleeved by and slidably connected to the outer sleeve and includes at least two engaging holes, plural second concave portions, and plural second protruding portions. The second protruding portions are slidably connected to the first concave portions respectively, and the first protruding portions are slidably connected to the second concave portions respectively. The jointing ring is movably connected to the outer sleeve and includes an abutting part and an accommodating part, and the abutting part optionally abuts against the abutting ball. By controlling the jointing ring, the inner sleeve can be slid or positioned relative to the outer sleeve, and the length of the telescopic socket can be changed.

An apparatus for removing lug nuts for changing a tire on a vehicle has a bracing structure and at least three arms connected to the bracing structure. A first arm extends upward and a second arm, adapted to operate as a footrest, extends outward and both arms are positioned such that one may stand on the second arm to generate extra torque while grasping the first arm for stability. A third arm is adapted to receive a socket and is oriented along the socket's axis of rotation. All arms are collapsible for storage.

An insulated screwdriver includes: an insulator, a first metal sleeve, a second metal sleeve, an insulated sleeve, and a handle. The insulator has a first connecting portion and a second connecting portion. The first metal sleeve is disposed on the first connecting portion of the insulator. The second metal sleeve is disposed on the second connecting portion of the insulator, and the second metal sleeve and the first metal sleeve are insulated. The insulated sleeve covers the insulator, the first metal sleeve, and the second metal sleeve. The handle has an accommodating hole for accommodating the insulated sleeve. According to the insulated screwdriver of the present invention, because the first metal sleeve and the second metal sleeve are insulated, there is no electric shock danger for a user, and safety in use of the insulated screwdriver of the present invention may be improved.
